Question

我有两个型号。第一个模型包含数据库中的每个记录。第二个模型包含记录中的最高金额。

如何在一个视图中获得两个模型？我是Asp.NET MVC的新手，只是试图掌握它。

这是代码。

模型

namespace CharitySite.Models
{

    public class Charity
    {
        public int ID { get; set; }
        public string DisplayName { get; set; }
        public DateTime Date { get; set; }
        public Double Amount { get; set; }
        public Double TaxBonus { get; set; }
        public String Comment { get; set; }
    }

    public class CharityDBContext : DbContext //controls information in database 
    {
        public Charity Highest { set; get; }
        public DbSet<Charity> Donations { get; set; } //creates a donation database
        public CharityDBContext()
        {
            this.Highest = new Charity();


        }
    }

}

控制器

namespace CharitySite.Controllers
{
    public class CharitiesController : Controller
    {
        private CharityDBContext db = new CharityDBContext();

        // GET: Charities
        public ActionResult Index()
        {
            var AllDonations = new CharityDBContext();
            var all = db.Donations.OrderByDescending(s => s.Amount);
            if (all.Any())
            {
                //Get the highest amount record
                var h = all.First();
                AllDonations.Highest.DisplayName = h.DisplayName;
                AllDonations.Highest.Amount = h.Amount;
                AllDonations.Highest.Comment = h.Comment;
            }

            return View(AllDonations);
        }

查看

@model IEnumerable<CharitySite.Models.Charity>
@model CharitySite.Models.CharityDBContext



@{
    ViewBag.Title = "Index";

}

<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/bootstrap.css")" rel="stylesheet" type="text/css" />
<div id="header">

    <h1>Syria</h1>

</div>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<div class="table-title">
    @Html.Partial("_Database", Model);

</div>

您可以使用两个模型的属性创建自定义类，如下例所示：

public sealed class CharitiesIndexViewModel {
     public List<Charity> Charities { get; set; }
     public Highest Highest { get; set; }
}

之后，在您的视图中，您可以使用它：

@model CharitiesIndexViewModel
